Title: Disc device for optical erasing
Inventor: ITO NOBORU
IPC: G11B7/135
Filed: 1985-03-01
Abstract: PURPOSE:To erase signals efficiently by forming a quickly heating spot and a gradually cooling spot with one light source in consideration of the shape of a prism. CONSTITUTION:The optical beam emitted from an erasing semiconductor laser 2 is converted to parallel rays 21 by a condenser lens 4 and is made incident on an erasing beam forming means 20 and is divided to parallel rays 22A and a luminous flux 22B having a spread which are different in course. These luminous fluxes 22A and 22B are reflected on a deflecting beam splitter 8 and are transmitted through a quarter-wave plate 10 and are reflected on an optical filter 11 and are transmitted through quarter-wave plates 9 and 10 and the splitter 8 and reach an aperture lens 12 to form an erasing spot 23. At this time, luminous fluxes 22A and 22B incident on the lens 12 are different in incidence angle to form light spots 23A and 23B in different positions, and a disc is quickly heated by the spot 23A having a high energy density and is cooled gradually by the spot 23B having a low energy density thereafter, thus erasing signals most suitably.

Filed: 1989-02-22
Abstract: PURPOSE: To make it possible to control the flow of material by providing the apparatus with a rotating hollow drum formed of a plurality of rings spaced at a predetermined distance from each other in a longitudinal direction. CONSTITUTION: The material to be classified is supplied to an inflow pipe 18 from which the material is sent to the center of a tubular main body section 12.

Simultaneously the material is made to flow downward toward an outlet side by ascending of the tubular main body section 12 and is collected into an oversize material collecting pipe 22. The material first flows through an initial classifying section 24 for segmenting the small material, from which the material is sent to a central mixing section 26 in order to intensify the mixing. The material flows therefrom to a final classifying section 28. A sensor 74 regulates the flow of the material through the tubular main body section 12.

Title: Control device for clutch for fluid coupling
Inventor: KUBO MASAHIKO
IPC: F16H61/10
Filed: 1995-02-28
Abstract: PURPOSE: To provide a control device for a clutch for a fluid coupling which is so constituted as to suppress transmission of a rotation fluctuation and a torque fluctuation to a car body as much as possible as durability of a damper clutch and a fuel reduction effect by rest cylinder operation are ensured. CONSTITUTION: When an engine 1 is operated in a rest cylinder permission region, a TCU 6 performs control of a slip according to a slip direct coupling control area enlarged compared with a rest cylinder non-permission region, and meanwhile, even in a slip direct coupling control area, when an engine load is low, complete direct coupling control is effected. This constitution, even when the rotation fluctuation and the torque fluctuation of the engine 1 occur, prevents the fluctuations from transmission to an automatic transmission due to the slip of a damper clutch 28 and prevents vibration of a car body. Further, since complete direct coupling control is effected during low load running wherein generating torque of the engine 1 is low, durability of a clutch and reduction of fuel consumption can take place without damaging a riding feeling.

Abstract: PURPOSE:To simplify an apparatus and enhance function by integrating a bioreactor, a diffuser and a separated membrane module. CONSTITUTION:After being sent from a raw water tank 1 to a bioreactor 2, raw water is treated biochemically under aerobic microbic conditions. Next, by actuating a vacuum pump 14, a suction is carried out from the bioreactor 2 to a vacuum tank 8 for water to be treated through a separated membrane module 3. By said process, solid content is removed, and only filtered treating water is sucked and drained. When treating water is stored in the vacuum tank 8 up to water level to be detected by a level switch 21, treating water discharge valve 7 and a vacuum pump connecting valve 12 are closed and a discharge valve 2 is opened to drain out treating water down to a treating water tank 19. Thus an apparatus is simplified and the cost is reduced.

Inventor: NAKATSUKA SATORU
IPC: H02K15/03
Filed: 1992-02-27
Abstract: PURPOSE:To obtain a permanent magnet rotor having such a magnetic characteristic that the intensity of its surface magnetic field has no variability due to a draft angle without giving any adverse influence to the productivity by forming at least one hole through the disc section of a permanent magnet and forming the ring section of the magnet so that the ring section has no draft of molding with a mold.

Title: Car bumper
Inventor: JIEEMUZU ERU SUMIZEKU
IPC: B60R19/02
Filed: 1990-02-23
Abstract: PURPOSE: To effectively absorb energy by providing a module adapted to absorb the impact energy of a collision face by distortion of walls and ribs, buckling of a rail and the subsequent deflection. CONSTITUTION: In a bumper 20, at the time of a collision, first a horizontal rail 34 just starts to bump against a rear support plate 21, and only the upper and lower ribs 31, 32 along the walls 26, 27 are operated to absorb the force. Secondly, the rail 34 starts to be bent similarly to the ribs 31, 32, and the walls 26, 27 are further expanded. In the module 24 deformed to the maximum, the ribs 31, 32 and the walls 26, 27 are completely extended so that the force applied to the rail 34 deflects the rail to the extension area. In this case, the bumper 20 absorbs much more energy, and in a small deflection area, the force is large. Then, in a large deflection area, the force is rather constant, thereby making the work close to an ideal curve to be maximum.

Title: Stationary induction electric apparatus
Inventor: HIDA TOSHIO
IPC: H01F27/28
Filed: 1983-03-15
Abstract: PURPOSE:To form a multitude of cooling ducts and realize excellent cooling effect of insulating coolant over the whole windings uniformly by a method wherein grooves are formed on a metal foil by winding insulation tapes helically on the foil with a preset interval and this metal foil is wound, while being laminated with an insulation sheet, to form a foil winding. CONSTITUTION:Insulation tapes 10 are wound helically on a metal foil 3 to the width direction with a preset interval (d) so that a multitude of grooves whose depth is the thickness (t) of the insulation tape 10 are formed in parallel along the width direction of the metal foil all over the surface of the metal foil 3. The metal foil 3 is laminated with an insulation sheet 4, which is made of a thin synthetic resin sheet of the thickness t' and width a little wider than the metal foil 3, in order to maintain the insulation between the turns of the lapped metal foil 3. The laminated metal foil 3 and the insulation sheet 4 are wound around an insulation cylinder provided around a core. The parts where the insulation tapes 10 are not wound form approximately rectangular gaps 11 together with the surrounding insulation sheet 4. A multitude of these gaps 11 are formed with a preset interval l to provide cooling ducts into which insulating coolant is introduced when the transformer is in operation.

Title: Parts-intertwinement preventive method of parts-feeder and parts-feeder
Inventor: ADACHI KAZUHIRO
IPC: B65G47/14
Filed: 1994-03-11
Abstract: PURPOSE:To provide a parts-intertwinement preventive method of a parts-feeder, and a parts-feeder in which parts can be separated to each other by intermittently applying a pressure to a mass of parts that have been stuck to each other inside a vessel by the influence of oil, static electricity, or the like. CONSTITUTION:When the O-rings 21 that have been stuck each other to form a mass are returned to the curved surface part 3a of a vessel 3 by means of a guide plate, since the O-rings 20 are not supplied to a linear conveying route, a sensor part detects none of O-ring 20, and sends a detection signal to a control part. While receiving the detection signal, the control part turns ON a vibration driving part 2 for vibrating the vessel 3, and at the same time opens a solenoid valve for approximately 5 seconds, for instance, at intervals of 60 seconds, so that the air from an air source is supplied to the air inlet/outlet port 5b of a pressing part 5 for pressing down a pressing plate 5f together with a coil spring 5e. Since the pressing plate 5f presses the O-ring 21 that is stayed in the conveying route directly before the guide plate, the O-ring 21 is separated into individual O-rings 20, so that stagnation can be eliminated.
